The column lock is not related to the body style, it's the transmission that dictates whats fitted. You have a 99 MN6 so its affected but even the automatic gearboxes on 99s had the lock.
This is the TSB that describes the original GM fix. Since then they've issued 4006B and 4006C to try to fix it. If you can't hear the column lock working and the steering doesn't lock you may have had one or all of the mods done. If in doubt, the Column Lock Bypass is a cheap and reliable fix for $50.

MODELS:
CERTAIN 1997-2004 CHEVROLET CORVETTE EQUIPPED WITH A MANUAL TRANSMISSION, 1997-2000 CHEVROLET CORVETTE EQUIPPED WITH AN AUTOMATIC TRANSMISSION, AND CERTAIN 2001-2004 CHEVROLET CORVETTE EQUIPPED WITH AN AUTOMATIC TRANSMISSION – EUROPEAN EXPORT ONLY.
DESCRIPTION:
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 1997-2004 model year Chevrolet Corvette vehicles. When you remove the ignition key, the electronic column lock (ECL) system prevents turning of the steering wheel. When the vehicle is started, it unlocks the steering. Two conditions can prevent steering while the vehicle is moving:
1. The vehicle is designed so that if the column fails to unlock when the vehicle is started, the fuel supply will be shut off if the driver tries to move the vehicle. If voltage at the powertrain control module is low or interrupted, however, the fuel shut off may not occur and the vehicle can be accelerated while the steering is locked.
2. During quick cranks, the ECL lock pin may not withdraw fully and, in vehicles where there is abnormally low clearance to the lock plate, there may be contact between the pin and lock plate. This can cause a noise or ratcheting when the steering wheel is turned or, if there is insufficient clearance, the steering wheel cannot be turned.
